Title: Feeding device for manufacturing catv cable
Inventor: SASAKI TAKASHI
IPC: H01B13/00
Filed: 1991-08-26
Abstract: PURPOSE:To prevent generation of a slippage between belts and a cable, and the flatening of the cable, by providing recessed grooves to which belts are pressed so as to increase the contact with the cable, into the pulleys to rotate the belts. CONSTITUTION:Recessed grooves N are provided at the center of a driving pulley 9 and an upper side driven pulley 13, that is, at the top parts of the crown, along the whole periphery. The recessed grooves N have a specific curvature. Since a feeding device is operated to pull out a cable (cable for CATV) M, the upper belt 11 and the lower belt 15 are deformed depending on the pressure contact force to the cable M, when the belt M is held between the belts 11 and 15, and they are pressed in together with the cable M in the recessed grooves N in the close contacting condition. Consequently, the contact area of the cable M to the belts is increased without flatening the cable M.

Title: Semiconductor memory circuit
Inventor: MIZUKAMI TAKESHI
IPC: G11C11/34
Filed: 1984-11-13
Abstract: PURPOSE:To obtain a large reading signal without enlarging the capacity of a cell by setting the reference potential lower than the threshold value of an FET for writing/reading. CONSTITUTION:The reference potential Vs is set lower than the threshold voltage of FET-Q. When reading information, a bit line B is charged to high potential VDD, and a word line W1 is set to high potential, and a memory cell MC1 is selected. If the MC1 stores '1', a contact N1 is VDD, and distribution of charge between the line B is not made and accordingly, Q remains non- conductive. If the MC1 stores 'O', the contact N1 is in grounding potential, and charging is made from the line B, and the potential of the contact N1 rises. At this time, the potential of a contact Nr is also raised by the capacity Cs and Q becomes conductive. Accordingly, by adjusting time constant of Cs-R, a large output can be obtained easily.

Title: Dynamic pressure fluid
Inventor: NAKAOKA MASAKI
IPC: H02K5/16
Filed: 1983-12-19
Abstract: PURPOSE:To aim at enhancing the durability of a thrust member in a dynamic pressure fluid bearing for a polygon drive motor, by combining a stepped section coaxial with the bore of a sleeve, with the thurst member having a spherical contact surface. CONSTITUTION:A rotary sleeve 102 secured thereto with a polygon rotor is formed in the inner surface thereof with a stepped section 102 as a thrust member receiving section on which a spherical contact surface 107 of a thurst member 7 is confronted so that the apex of the spherical contact surface is accurately positioned at the center of the circular stepped section 102a. This thrust member 107 is pressed by means of a retaining ring 120 having a threaded part. However, since an excessive pressing force causes the thrust member 107 to be deformed, a damper member made of materials such as, for example, rubber, is disposed between the thurst member 107 and the retaining ring 120. With this arrangement, the eccentricity of the pivot axis of the thrust member is prevented, thereby the durability of the thrust member may be enhanced.

Title: Supporting and fixing method for getter of cathode-ray tube
Inventor: YAMAMOTO YUTAKA
IPC: H01J29/94
Filed: 1988-09-22
Abstract: PURPOSE:To fix a getter stably in a specified position of a funnel, stabilize the quality, and enhance the working efficiency by allowing a frame, which is fixed to the inner wall of the neck near its end continued to the funnel, to support the getter in the funnel with the aid of a supporter. CONSTITUTION:A frame 8 is fixed to the neck 5 at its end close to the funnel 4, i.e., apart from the electron gun 1, which shortens the length of a supporter 2 compared with the conventional arrangement in which it is fixed to the electron gun 1. This provision of frame 8 near the funnel 4, as apart from the electron gun 1, allows stable supporting/fixing of a getter 3 in the desired place, which shall be approx. in the center of the funnel 4, in stable condition. Also a relatively short supporter 2 ensures stable supporting/fixing. Because the bent point of the frame 8 and supporter 2 is short, it 2 will never approach the electron beam passage which is identical to the tube axis.

Title: Image processor and image processing method therefor
Inventor: KOBAYASHI KUNIHIKO
IPC: H04N1/46
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an image processing unit that production of unintended color conversion is avoided in the case of logic arithmetic processing so as to obtain a processed image with high image quality. SOLUTION: For this image processing unit, an input color conversion section 1 converts an RGB color space into a CMYK color space, a 1st color conversion section 2 converts the converted color space into a CMY color space regarding an object area for logic arithmetic operation processing, and a logic arithmetic section 3 conducts logic arithmetic processing. Then a 2nd color conversion section 4 converts the logical arithmetic result into a CMYK color space. Meanwhile, a pixel value comparison section compares color values in the CMY color space before and after the logic arithmetic operation by the logic arithmetic section 3, and an output image selection section 6 selects the color value that has been color-converted by the input color conversion section 1, if they match.  Thus, when the color value of the image is not changed as a result of the logical arithmetic processing, since the color value in the original CMYK color space is adopted for an output result, unintended color conversion by the 1st and 2nd color conversion sections 2, 4 will not be generated.
